N/A Effect of airway humidifiers on the respiratory parameters and arterial blood gases. Intervention 1: Intervention group: The eligible patients of the study are divided into two groups – namely; the first and the second group- according to the random number table; one of the airway humidification devices is used randomly as an intervention for the first group, for 30 minutes, then the results are recorded and the second airway humidification software is used for 30 minutes and its results are recorded as well. Intervention 2: Intervention group: One of the airway humidification devices is used randomly for 30 minutes as an intervention for the eligible patients of the study who are placed in the second group according to the random number table, then the results are recorded and the second airway humidification software is used for 30 minutes and its results are recorded as well. In fact, we have an intervention group that is randomly divided into two groups, and both airway humidification devices are used randomly in a crossover manner, each for 30 minutes.
